You can borrow wallpaper books from suppliers and compare some you like by holding the samples up to your walls. Be sure to test how well they complement each other at different times of the day under different light conditions. I know it's hard to know for absolute certain how a particular wallpaper pattern will look on a large scale, but it's a place to start. And the people at the decorator stores will be happy to advise you.

Yeah. I agree with Hayley. Upload it into an ideabook and then i think you can use colour picker

there are some interesting putty grey colours in the knots of your floorboards. I reckon it would be worth holding some paint swatches up to the boards and see if you can find one that ties in with those driftwood tones in the timber . Then order a sample pot in a half or quarter strength version of the matching colour then see how it looks. Otherwise it is so hard to go with colours people have named, as every space has different light. If you are happy with the colour of the floor boards, let them guide your choice and you can't fail (as long as not too dark). :)

@dreamer yes I was thinking a simple timber balustrade would look better than a more modern one. we are planing on putting a covered deck off the back with a similar balustrade too. @fianou Luca I love fixed upper. They were the reason we bought this house as I could see the potential. it is much harder than it looks go bring a look all together. I was contemplating painting the brick lighter like a wash but to scared to vomit incase it looks terrible and it is an expensive job to do. I was even thinking of putting shutters on the windows downstairs to give the front some texture
